A Deadly Paradise — Grace Brophy

In the peaceful Umbrian village of Paradiso, the shocking murder and mutilation of an elderly German woman is barely credible. That is, until Inspector Alessandro Cenni of the State Police discovers that this retired cultural attach was not just a difficult tenant, but also a bisexual swinger with an African lover recently in residence, as well as a blackmailer. The dead woman grew up in occupied Venice, and some of her secrets may have been acquired that long ago, during World War II. And the bucolic village is not that innocent: It was the site of a famous, scandalous murder fifty years earlier.

Cenni's boss wants a scapegoat, and the young African lesbian is the obvious target, but Cenni cannot bring himself to close a case without solving the crime and bringing the actual perpetrator to justice.
